A hybrid theoretical/experimental approach to the design of radial line slot array (RLSA)
antennas for receiving direct broadcast satellite (DBS) TV programs in Australia is …

The standard linearly polarized radial-line slot-array (RLSA) antenna exhibits poor return
loss as seen by its coaxial feed. This paper describes techniques that improve the poor …

Recently, ridge gap waveguides are considered as guiding structures in high-frequency
applications. One of the major problems facing this guiding structure is the limited ability of …

This paper presents a computer-simulation-based design of an in-line, coaxial-to-circular
waveguide adapter for converting the coaxial transverse electromagnetic (TEM) mode to the …

The design and fabrication of a 10.5 GHz microstrip patch array fed by a waveguide is
presented. The gain of this antenna is 29 dB and its efficiency is 65%. Commonly, the …

Coaxial to waveguide transitions play an important role in high frequency systems. The
